-Wit-h these and-other-objects in view,'=the'in vention resides in the combination, arrangement and functional relationship of elements as set forth in the following specification and particularly pointed out in the appended claims.

In the accompanying drawing,

Figure 1 is a plan view of a toilet showing the present invention applied thereto;

Figure 2 is a view of the toilet in side elevation with the invention applied thereto;

Figure 3 is a fragmentary vertical sectional view taken on the line 3-3 of Figure 1; and

Figure 4 is a bottom plan sectional view taken on the line 4-4 of Figure 2. v

Referring specifically to the drawing, a ventilating unit or adapter designated generally at V, is shown applied to the toilet bowl B of a toilet of well known construction whose seat S has a relatively narrow tail piece 60 to which is secured by screws 6|, upstanding bearing arms 62 between which projects a tail piece 63 on the cover C having a pivot pin 12a extending of the 1 housing portion fla to define a duct 36a having an inlet 31a at the rear "portion 0f 2th ="bowl as elearlyshowninIFigureI3. 4 I

'Th'e ttop wall 2 5a is out iaway t'o -receive :the

taili-piecei60 of time seat-Sf, which =-pro,iectsiinto the rtubular portion a in the lowered :position of the seat. TFhe cut-away portion of the :top wall a is -sha'ped to provide -*a su'fllciently-c'lose tllt ag ainst the: confronting :portion of the seatzs' when lowered rontothe bowl as shawniin iFigure 2, to form a'satis'factory seal. v

Secured to the underside of the seat :e'my headed fastening members 50a, are gaskets or sealing members 5la of a contour to rest upon the rim IBa of the bowl in the lowered position of the latter, so as to seal the space between the seat and the bowl with the exception of a portion at the rear of the bowl corresponding to the width of the duct a at its inlet 31a, and a portion at the front of the bowl to provide a fresh air inlet 54a, it being noted that the forward edges of the sidewalls 26a press tightly against the rear ends of the gaskets 5la for sealing contact therewith as shown in Figure 4.

Secured by screws 31a and a metal bar 320. to the tubular portion 20a adjacent the top of the opening 22a, is the attaching flange 33a of a tubular sealing member 34a constructed of resilient rubber or other suitable material. The member 34a spans the width of the opening 22a cup-shaped closure 44a is secured in the other end of the portion 20a. by a set screw 45a. The vent pipe 4 la is extended through the wall of the room, preferably to the outer atmosphere.

Any and all odors existing in the bowl when the toilet is in use, will be drawn into adapter V by natural thermal action, it being noted that the air inlet 54a between the forward spaced ends of the gaskets 5la insures a supply of fresh or unodorized air into the bowl and across the latter from front to rear to most eiTectively utilize the thermal circulation in removing all bowl odors from the premises.

By the provision of the construction and functional relationship of elements of the adapter V as above described, the invention can be applied and installed in the very restricted space remaining between the rear end of the tail piece 60 of the seat S and the front of the flush tank as will be apparent from Figures. 1 and 2, all without requiring any modification of this standard type of toilet.

I claim:

In a ventilated toilet, a bowl; a seat therefor having a tail portion; a ventilating adapter having a tubular portion with a peripheral inlet and with an outlet adapted for connection to a vent pipe; means for securing the adapter to the bowl; and means pivotally mounting the seat on the adapter, with said inlet disposed between the bowl and the undersurface of said seat and with the tail portion of the seat projecting through said inlet into said tubular portion when the seat occupies its lowered position on the bowl.

2. In a ventilated toilet, a bowl; a seat therefor having a tail portion; a ventilating adapter having a tubular portion provided with a peripheral inlet and with an outlet adapted for connection to a vent pipe; means for securing the adapter to the bowl; brackets projecting from said tubular portion; a pivot pin mounted in said brackets; and bearing arms projecting from the seat and receiving the pin -to pivotally mount the seat thereon with said inlet disposedbetween the bowl and undersurface of the seat, and with the tailportion of the seat projecting into said tubular portion through said inlet, when the seat occupies its lowered position on the bowl.

.respect to the bowl of the toilet.

3. In a ventilated toilet, a bowl; 2. seat there-. for having a tail portion; a ventilating adapter having a tubular portion provided with a peripheral inlet and with an outlet adapted for connection to a vent pipe; means for securing the adapter to the bowl; brackets projecting from said tubular portion; a pivot pin mounted in said brackets, bearing arms projecting from the seat and receiving said pin to pivotally mount the seat thereon with said inlet disposed between the bowl and undersurface of the seat,

and with the tail portion of the seat projecting into said tubular portion through said inlet, "when the seat occupies its lowered position on the bowl; and a yieldable sealing member secured to the tubular portion to span the top of saidinlet for sealing engagement by the tail portion of the seat when occupying itslowered position.

4. In a ventilated toilet, a ventilating adapter comprising: a tubular portion having a'lateral inlet and an outlet; attaching studs depending from the adapter for connection to the toilet bowl; baokets projecting from said tubular portion and adapted for co-action with a'pivot pin to mount a toilet seat on the adapter; and a sealing member spanning the top portion of said inlet for sealing engagement by the tail portion of the toilet seat when the tail portion projects into said tubular portion. g r V g 5. In a ventilated toilet of the type whose seat is provided with a rearwardly projecting tail portion, comprising: a tubular portion having a lateral inlet adapted to receive the tail portion ofthe seat, and provided with an outlet; attaching studs depending from the adapter for connection to the toilet bowl; and brackets on the adapter, adapted for co-action with a pivot pin, to mount the tail portion of the seat onthe adapter for rising and lowering movements with ANDREW REFERENCES CITED UNITED STATES PATENTS P.
